O038 / #883 LARYNGEAL MOTOR EVOKED POTENTIALS: CLINICAL BENEFIT IN VAGUS NERVE STIMULATION USING A SYNCHRONIZED PROGRAMMABLE IMPLANT: TRACK 3: VAGUS NERVE STIMULATION / TOOLS TO INFORM PATIENT CARE

Abstract

Vagus nerve stimulation (VNS) delivers electrical pulses to the brain via the left vagus nerve. This stimulation triggers laryngeal motor evoked potentials (LMEPs) through the activation of the recurrent laryngeal nerve, a branch of the vagus nerve. This study describes a set of devices that allow for real time recording the LMEP in a non-invasive, efficient, and easy-to-use manner. The analysis of such recordings, using the LMEP as a biomarker for vagus nerve activation, allows for improved therapy delivery and personalization of VNS.
